We were using the wrong coordinates, this fixes things to match the original gtk2 implementation.
You can see this error in action by using -vga qxl, however even after this patch the mouse warps in small increments up and to the left, -7x and -3y pixels at a time, until the pointer is warped off the widget. I think it's a qxl bug, but the next patch covers it up.
